Beyond Best-Fit, Spatial Compensation of Metrology Data

Edward West, Christopher Jamieson, Garrett Kelley

Current digital compensation techniques for uncontrolled boundary conditions such as profile at station lines and profile-per-unit-length (PPUL) fall short of accurately characterizing deformed flexible structures. Janicki Industries has developed Spatial...

2020 CMSC PRESENTATION: Case Study of a Fuselage Join Automation

Rob Flynn, Nathan McRae, and Spencer Thompson

A large jet fuselage consists of forward, center and aft sections which must be joined together.  The join process calls for a rough move to a “stage” position, automated measurements, and calculation of a transformation matrix to yield a move to...

X-Ray CT Proposed Measurement Study

Andrew Ramsey

World-class manufacturers have many metrology solutions at hand to help them ensure the quality of their parts and finished products. For many decades, the “gold standard” for accuracy have been coordinate measuring machines (CMMs). Increasingly,...

Simple Methods for Dynamically Testing Laser Trackers in the Field

David H. Parker

Laser trackers are typically evaluated under the ASME B89.4.19 and ISO 10360-10 standards using artifact standards under static conditions. Due to the requirements of the artifact standards, evaluations are typically beyond the capabilities of most laser...

Robotic Arm Calibration Using Laser Trackers

Joe Packer

Electroimpact uses laser trackers to compensate large-scale serial link robot arms to achieve a very high degree of positional accuracy using our “Accurate Robot Technology.” 3D laser tracker data is collected from hundreds of uncompensated robot...

Derivation and Guide to the Uncertainty in the Angle Between Two Planes

Jana Barker, Anthony Barker

Coordinate metrologists need to plan their measurements and estimate the resulting uncertainties before data collection in order to achieve needed precisions. We present the mathematical relationship between the calculated angle between two planes, least...

INTEGRATION OF LASER TRACKER SYSTEM IN BIW MEASUREMENT: A CASE STUDY IN AUTOMOTIVE INDUSTRY

Armağan Altınışık, Emre Bolova

Product and process quality assurance are challenging task due to increasingly narrowing product specifications. Coordinate measurement is one of the key technologies used in the area of dimensional control to inspect and improve the accuracy of produced...
